Wismarini No. 09 Pringsewu – Lampung, Indonesia website: www.stmikpringsewu.ac.id Abstract In this paper is described how the assembly process of designing and developing a series of inflatable candles microkontroller. The series based on electronics is a simple circuit that utilizes condenser microphone as a sensor. The use of these components are suitable for use in an application circuit electronic candles where the workings of this series starts from LEDs that analogous to wax and then lit using a pushbutton that analogy as lighters, and a flame from the LED can be extinguished by blowing. The concept of this series is simple but could be developed into a series of more innovative and interesting. One development is to add the output of the LED running that made candles burn more lively and interesting. Running LED of this circuit works by using a transistor as a switch that controls power of Az IC 368 and IC Az 418 M J. To simplify the development process, combination of a series of electronic candles with LED running can be simulated using the software Livewire and Proteus. Results of designing and developing a tool is not a new thing or that have not been found but the result of this achievement can be a source of inspiring in the world of electronics that can later be developed further so that it becomes a result of more recent example, lights out with once pat. Keywords : electronic candle, assembly design and development, condenser microphone, LED running and control 1.0 INTRODUCTION 1.1 Background of The Problems The electronic candle [Karisma Alfiansyah, 2014] is a close electronics with aesthetic value. This tool can be used at birthday events or as a tool to beautify the room. In the planning of electronic candle has a difficulty level that is not too complicated but requires precision and accuracy in terms of electronic circuit planning. The principle of candlelight in general is burning when burned by matches and matches when in the wind. Then it can be simply concluded that the electronics candle to be made has the same performance in wax generally only electronics candles produce the output of a flame instead of fire. In a study undertaken by Dien (2015), chrysanthemum is a short-day plant whose initiation and development of flowers are controlled by the length of the day. Chrysanthemum plants need more than 13-16 hours of light a day to keep growing vegetatively. In tropical regions such as Indonesia, these needs can not be met by the average sun light 12 hours a day, so it needs to be coupled with artificial lighting from electric lights that are usually done after sunset. Light Emiting Diodes (LEDs) are semiconductors that emit light when in an electric current. Semiconductors are materials that can act as conductors (electrical current carriers) and insulators (electric current outages). The LED light emits light solely by the movement of electrons in the material. LED lamps are made up of semiconductor materials / materials that emit light waves that can be seen by the human IJISCS | 67 eye and transmit them in large quantities. Semiconductor materials are wrapped in plastic so that the concentrated light is generated in a particular direction. The plastic covering material can also be colored, but this is only for aesthetics and reinforces the color display that results in this plastic coloring not affected by the color waves generated depending on the semiconductor material used. Chrysanthemum fiji variety wrapped in additional light yellow led lamps have high stem growth faster than other color LED light and LED colors for the growth of chrysanthemum plants ie red ledge, blue, yellow, while the LED light with blue and red color help optimize the process of plant photosynthesis than green. Electricity [Gunawan. S, 1995] is the main energy source in the community, almost all human activities can not be separated from the use of electrical energy. Along with the current economic and educational improvement, 20% of electrical energy is used for lighting, efficient use of lighting can result in cost observers and energy conversion. The magnitude of the voltage for the bright flame on the fluorescence lamp (TI) with electronic reply is 110 Volts, while for the flourescen lamp with the unreachable indicator reply is 180 Volts. So the most profitable electronic reply user is seen from the voltage. 1.2 Formulation of the Problems Based on the background of the problems, the problem can be formulated to serve as the discussion in this paper is how to develop an electronic candle that will produce the output of a flame LED. 1.3 Objectives Goal to be achieved of this paper are to find out old type of electronics candle and to knowing the candles that produce LED. 2.0 THEORETICAL 2.1 Microcontroller Concept Microcontroller is an intelligent chip that becomes a trend in control and automation that have many types of families, memory capacity, and features. Microcontroller becomes an option in mini-processor applications for small-scale control. In the final project, the authors used ATMega8535 AVR type. ATMega8535 microcontroller using RISC architecture (Reduced Instruction Set Computer), which means that processor has fewer program instruction set compared to MCS-51 implementing CISC architecture (Complex Instruction Set Computer) . RISC processor instructions, almost all of them are basic instructions (not necessarily simple), so these instructions generally require only one machine cycle to run them, except for branching instructions that require two machine cycles. RISC is usually created by a harvard architecture, because this architecture allows to make instruction execution done in one or two machine cycles, so it will be faster and more reliable. The process of downloading the program is relatively easy, because it can be done directly on the system. 2.2 Electronics Candle Everyone knows that candle is one of the things that can illuminate the darkness during power outages, not only that, candles are often used to celebrate a birthday party and some still use candles to celebrate a celebration on the big day. Here will be explain about electronic circuits that are electronic candles, candles made from some electronic components that can function as conventional candles, the way it works is similar to the usual candles in daily use, by replacing the fire (matches) in close proximity sensors, then the light will turn on and will not turn off before the light is blown on the censor, in other words how to turn off the electronic wax and even the same way to turn off the candle is generally in the inflatable.

By using this software can be known to work or not the circuit to be made. By using livewire the current direction of each component can be known so that simplify the circuit analysis process. 3.4 Series simulation by project board The experimental process using the project board is a final-stage experiment to make sure the components used are ready to be plugged into the PCB and soldered it to minimize errors when components are paired to PCB layout. 3.5 Development of electronic candles series The same development process must go through the experimental stage using the software. By using the software, series can look more real though just a virtual component. After the trial through the software is completed to further convince the experimental process can be done by using project board. 4.0 RESULTS AND EXPLANATION 4.1 Result of research Hardware testing involves several circuit blocks, and testing of a combination of several circuit blocks as follows: 4.1.1 Power Supply Testing Testing the power supply circuit by measuring the Vout of each regulator IC Az 368 M and Az 418 J using a digital multimeter.
